Sash hanger



July 15, 1952 J. J. REYNOLDS SASH HANGER Filed Nov. 24, 1950 JEN/V I REY/m4 o5 1 Gttomeg Patented July 15, 1952 --.-umreu STATE-,5. arms A ER r v J; Reynolds, East Orange N. J? i I I ""A'pplicati on Nove er 24, nausea no. 197,430 l h warms. :(cl. 16 1 72)- This invention relates to fixtures used on the outside of window frames to hang screens-and storm window sashes and toallow the sashes to swing on the fixtures as a hinge.

One of the prime desiderata .of such-fixtures is facility in hanging and removingthe sashes". Another and important desideratum' is safety or security of attachment of the-sash mpg-11 posi;

tions of use. Other general desidera ta aresimplicity of construction, economy in production cost and attractiveness of appearance:

The present invention satisfies these desiderata. Each hinge, or" which there will normally be two, consists of two sheet metal parts, one permanently attached to the frame of the window properly disposed immediately above. the opening, and the other attached to the upper sash rail and having an upwardly extending hook'portion to engage with a hanger portioncf the hinge part on the frame. In accordance with ,the invention the parts are;so constructed that the sash hingepart is guided into;interengag-ing relation with the cooperative framev hinge part as the sash is moved up in thegwindow frame at a slightinclination, so that the hook naturally catches over the hanger portion, as the sash is lifted up at this angle. The sashfwhich is then free to hinge ,on the hanger, is unrestrained against relative verticalmovement of the hinge parts until in the opening movement the sash leaves the window frame and is no longer under lateral restraint. Then the interengagement between the hinge members becomes inseparable. In other words, the hook portion of the sash hinge member separately engages the hanger portion of the frame hinge member so long as the angle of the sash is such that the sash is under lateral restraint, but the engagement is inseparable when the opening movement of the sash brings it outside the frame. This makes it easy to hang and remove the sash but prevents the sash from blowing off or being otherwise accidentally removed in its more widely open position where it is clear of the frame.

These features will appear more clearly from a consideration of the embodiment of the invention illustrated in the accompanying drawings in which Fig. 1 is an outside elevation of the upper portion of a window frame with a corresponding portion of a screen containing sash in the opening attached and hung by a hinge construction embodying the invention.

1 In Fig. 1 two hinge. fixtures are ishownwhich is the usual-number. The screen s'ashl ilsis shown in the-window opening attached by-the fixturesto. the top'member of the window frame H, :the. screen being disposed outside the slidingv window:

sashes l2 and I3. Since the twofhinge construe tions are the same ar description of: one will suffice. a

formed 'of a strip of: sheet metal shaped fashioned for'its particular function;

The frame-hinge part [.4 comprises 1av fiat-metallic strip bent on a transverse line to form a.

plate portion lfi Which is: attached by screws .to the frame member H, and a hanger portion I'lsomewhat shorter than the plate portion and extending upwardly and outwardly at an acute angle from the bottom of the plate portion. Near its top edge the hanger portion l! is provided with a transverse slot It, the metal for the purpose being cut along the top and two ends and turned inwardly to form a lip I9.

The sash hinge part l5 comprises a flat metallic strip of substantially the same width as that of the frame part 14, which is bent on a transverse line to form aplate portion 20 which is attached by screws to the top rail of the screen sash l0, and a hook portion 2| extending upwardly and outwardly from the top of the plate portion at an obtuse angle which is a supplement of the acute angle between the two elements of the frame hinge part, as shown in Fig. 2. At its top the hook portion is reduced in width to substantially the length of the slot I8, and the narrow extension is bent inwardly to form an arcuate hook 22.

The arcuate length of the hook 22 is such that it engages in the slot l8 only when the sash is opened outward to a substantial angle to the vertical, beyond that necessary for hanging or removing the sash. The parts are so designed and proportioned that the hook begins to enter the slot in the opening movement of the sash approximately as the top of the sash leaves the window frame opening which is approximately the position shown in Fig. 3. Up to that position the sash may be lifted off. And in applying it, the sash is guided in the frame so that the hooks come into registry with the slots.

The slot I8 is so disposed and the hook 22 is formed to such a radius that the hook bears on the lip l9 and the hook clears the top edge of the hanger portion 11, as shown in Figs. 2, 3 and 4. Thus friction in the hinging action is minimized. The lip desirably is made arcuate concentric with the axis of the hook and constitutes the bearing on which the hook turns.

It is apparent that the hinge parts must be properly located for cooperative action. For this purpose a suitable template may be employed for spotting the screw holes, and, if desired, locating arms may bestruck out and bent in from one or both of the parts, in the one case to bear on top of the sash and in the other case to bear on the bottom face of the top frame member.

It is to be noted that by virtue of this construction the suspension radius of the sash is of such length and the hinging axis is so located above and in front of the sash that there is a substantial downward component of movement to the sash at the beginning of its opening movement, as shown in Fig. 3.

. As shown in Fig. 2, when the sash is hung and is closed, the hook portion 2| is parallel and in close proximity to the hanger portion I1. When the sash is applied, it is grasped at its lower end and entered with its top end into the frame opening and is lifted up until the hook 22 strikes the hanger portion I1 and rides up that face until the inwardly turned hook catches over the top of the hanger portion. The sash is then hung and can be removed only by lifting the hook off the hanger portion. The lateral guiding of the sash assures that the hooks are in position to engage in the slots as the sash is further opened.

While the invention has been described in connection with a suitable embodiment thereof, it will be understood that the invention is not limited to this form in all particulars but that changes will occur to those skilled in the art 4 which come within the principle and scope of the invention as defined in the following claims.

I claim:

1. A sash hanger including interengageable frame and sash members, the frame member having a plate portion securable to a window frame and a hanger portion extending upwardly and outwardly at an acute angle from the plate portion, the hanger portion providing an outstanding free edge at its upper end and having a transverse slot near said edge; and a sash member having a plate portion securable to a sash and a hook portion extending upwardly and outwardly from the plate portion at an obtuse angle which is substantially the complement of the said acute angle, the upper end of the hook portion constituting a hook and being curved inwardly in the form of a hook through an arc exceeding and the hook portion being of a length to engage with its hook upon the free edge of the said hanger portion when the two plate portions are in the same plane, the slot being proportioned to receive the hook and the radius of curvature of the hook being substantially half the distance of the center line of the slot from the said free edge, whereby the end of the hook will enter the slot when the hook bears upon the said free edge upon outward rotation of the sash.

2. A sash hanger as defined in claim 1 in which the hanger portion has an inwardly extending guide lip coincident with the bottom edge of the slot to guide the end of the hook into the slot.
